Title: Improvements in Compounf Multiple expansion Rotary Engines
Inventor: HARDINGHAM GEORGE GATTON MELHUISH
Filed: 1901-04-04
Granted: 1902-04-03
Abstract: 7191. Hardingham, G. G. M., [Johnson & Cn., W.]. April 4. Roots'-blower type.-A multiple-expansion engine of the Roots'-blower type is shown in Figs. 1 and 2. The casing A is divided into four working chambers e<1>-e<4> by partitions c formed with passages c'. Each chamber contains a pair of engaging wings f<1> mounted on the shafts F<1>, which are geared together by discs i<1> similarly shaped to the wings. The wings are preferably shaped as shown in half- sectional view in Fig. 8, and fitted with lateral packing-strips g pressed outwards by coiled springs g<1>. End packing, consisting of two strips g<2> pressed outwards by a spring-pressed bar g<4>, may be fitted to the wings. Motive fluid is admitted by the supply port j to the high-pressure chamber, and then passes through the passage c<1> to the other chambers in turn. To facilitate starting, the motive fluid is conveyed direct to the low - pressure cylinders by means of valve-controlled pipes k, which are subsequently closed. A balanced ex- pansion valve m is actuated by a rocking lever m<1>. A cam on one of the shafts F<1> is connected by a lever m' and link m<3> to the slotted end of the rocking lever, and the position of the link in the slot, and thus the cut-off of the valve, are governed by a governor M, which is connected by the lever m<10> to the link m<3>. The pressure between the two sets of engaging wings is regulated by supporting one of the shafts F' in bearings h, which can be ad- justed by means of springs h<1> and set-screws h'. In a modification, the lateral packing on the wings is dispensed with, and the partitions between the working chambers are made expanding and supplied with the motive fluid. The engine may be made reversible by fitting D-slide valves to the sides of the casing and suitably connecting the motive-fluid passages.

Abstract: 9730. Nolan, J. H. May 10. Beer and other beverages, raising and drawing-off.- Beer, ale, or other liquor is forced, by compressed air supplied from a duplex pump compressor 2, through pipes 1, 6 controlled by valves 20, 7, up pipes 8 leading to delivery faucets 10. The pipes 8 have coils in a tank 9, which may contain ice. Liquid may be forced down the pipes 8 by compressed air fed through pipes 12, 14 controlled by a valve 19. Non-return valves 13 are provided in the branches 14 to prevent liquid from entering the air pipes. The compression is regulated by a weight on a pivoted lever connected by a rod to a diaphragm in a chamber communicating with the compressed-air pipe. The lever is also connected by a rod and bell-crank lever to a horizontal rod connected to and operating a switch in the circuit of an electric motor which operates the compressor. The horizontal rod is made in two parts, the adjacent ends of which have slots engaged by a pin on a pivoted weighted member which is operated by one part so that, when overbalanced, it operates the other part suddenly, so as to prevent sparking at the switch.

Abstract: 1990. Dowson, J. E. Jan. 24. Gas - producers ; a i r supply, heating.-The air to be used for the production of producer gas is heated :-(1). by the exhaust from the engine using the gas, (2) by the hot gas produced in the generator, or (3) by both exhaust and hot gas. In the arrangement shown, air is drawn at f into the casing a, surrounding tubes c heated by the engine exhaust, and leaves this heater by an outlet g. It then passes up a number of tubes l to a top chamber k, whence it is driven by a jet of steam, entering at p, down a central tube o, and thence into the generator h. The hot gases leaving the generator pass through a tube m to a casing i surrounding the tubes l and o, and then pass away through the outlet n. Instead of a steam jet, a fan or blower may be used to force the air through the apparatus. The air-heaters may be horizontal or inclined. An air-heater such as described in Specification No. 23,134, A.D. 1901, [Abridgment Class Heating], may be used.

Title: Improved Apparatus for the Mechanical Determination of the Linear Elements of Triangles for Telemetric Purposes.
Inventor: LOCK WILLIAM HENRY
Filed: 1902-03-20
Granted: 1903-03-19
Abstract: 6838. Lock, W. H., Pollen, A. H., and Barr, M. March 20. Telemeters.-Relates to mechanical apparatus for the determination of the linear elements of triangles, for telemetrical purposes, which is based upon the following trigonometrical principles :- In the triangle, Fig. 1, If, now, along inclined axes 0 P, 0 Q, Fig. 2, lengths o c, o a, and o b are set off, equal, respectively, to constant multiples of the quantities S. sin (A-B), and sin B, then, by drawing d b parallel to a c, the length L will vary as the length R ; i.e., if R is the distance of an object E from the base line S, it can be determined from the length L. The solution is effected mechanically by the apparatus shown in Fig. 5. In grooves 3, 4 the pivots a, b, c, d, of two bars 1, 2 are adapted to slide and be adjusted. These bars are constrained to move parallel to one another. Since, in practice, the angle A-B is never more than about 36', the distance o a is set off against an angular scale 15 by means of a screw 5 and micrometer head 18 acting directly on the pivot a. In the case of the pivot b, however, used for setting off the value of sine A, the adjusting-screw 6 acts upon it through the intermediary of a sine-cam 10. The corresponding angle is read off on the scales 11, 12. The distance o c corresponding to the base length S is set by a screw 7 and micrometer head 24 against scales 20, 25. To determine a range, therefore, the pointers 20<a>, 25<a> are first set to the base employed. Of the angles A, B, the first is then set off with the pointers 11<a>, 12<a>, and the difference between it and the second against the pointers 15<a>, 16a ; the range R is then read off directly on the scale 19 opposite the pointer 19<a>.

Patent GB-190216896-A (GB)
Title: Improvements in Electrically Controlled Semaphore Signals for Railways.
Filed: 1902-07-30
Granted: 1902-12-04
Abstract: 16,896. Siemens Bros. & Co., [Siemens & Halske Akt.-Ges.]. July 30. Semaphore signals; controlling and locking signals. -Relates to means whereby the movement of the semaphore arm into the line clear' position is made dependent upon the existence of a current of a definite minimum strength in a certain electrical circuit. As shown in Fig. 1, an articulated parallelogram, pivoted at a fixed point 3, is interposed in the operative connections, and carries the armature 2 of the fixed electromagnet 5, the actuating-force being applied directly or indirectly to the member 1, 2, e.g. at the point 1. When the magnet is energized sufficiently to hold the armature, the actuating-force will rotate the member 3 and lower the signal. If the magnet is not energized, the actuating-force will collapse the parallelogram on its diagonal 1-3 without affecting the signal. If the magnet is de-energized when the signal has been put to line clear,' the signal will be returned to 'danger' by its counterweight. The connection of the parallelogram with the semaphore and the actuating-mechanism may be reversed. The armature member 2 and the member 3 may have separate fixed pivots. To prevent the semaphore, if accidentally brought to 'danger,' from being put back to 'line clear' so long as the actuating-mechanism is in the line ' clear ' position, the locking-mechanism shown in Fig. 7 is employed. The locking-pawl 8 does not prevent the normal movement of the lever 12 which lowers the signal, but, if the signal is at normal when the actuating-rod 9 is in the line 'clear' position, the pawl 8 engages the fixed surface 11, and prevents any movement of the lever 12, and consequently of the signal. To prevent the armature 10 from being brought too violently against the poles of the magnet, the member 1, 2 is articulated, as shown, or it may be formed by a chain or rope, so that it can be deflected laterally. Fig. 9 shows another arrangement of the operative linkage. In the modification shown in Fig. 10, the links 4-3, 14-13, Fig. 9, are replaced by fixed guides 15, 16, the operatiugrods having a rectilinear motion.
